HYDROKINETIC ENERGY · DELFT
Power from
shallow water.
Miromar builds hydrofoil generators for channels too shallow for turbines. We start in irrigation canals and scale to tidal channels.
Lab-validated model (TRL 3). Full-scale prototype in 2027.
WHY IT WORKS
Turbines need depth.
Most moving water doesn’t have it.
Canals and many tidal channels are wide and only a few metres deep. A conventional rotor is round, so the available depth limits its diameter and the amount of moving water it can reach.
Miromar starts with the shape of the channel. A row of hydrofoils extends across the flow, using width where a large rotor cannot fit. The distinction is geometric, and it is the foundation of the machine.
Rotor: limited by depth
Miromar: spans the width
HOW IT WORKS
A generator built
around the channel.
Each hydrofoil heaves and pitches as water passes it. That motion drives a generator below the surface. The system is designed to operate with flow in either direction, without turning the module around.
The same principle connects two distinct markets. In a canal, the machine works with managed flow and accessible infrastructure. In a tidal channel, the direction reverses with ebb and flood.
Miromar is developing the generator as a modular system that can be transported in standard shipping containers and installed without asking a water operator to change the primary function of the site.
STATUS
The model matches the lab.
The next test is full scale.
Miromar has validated its numerical model against controlled flume experiments, reaching TRL 3. This establishes that the model describes the measured hydrofoil behaviour under laboratory conditions.
The model predicts up to 4.75 kW peak output for an eight-hydrofoil canal module. That is a modelled result, not a measured full-scale output.
The full-scale prototype planned for 2027 is the next engineering step. Its purpose is to measure the complete system at the size intended for deployment and to provide the evidence required before a site trial.
MARKETS
Canals are the first market.
Tidal channels are the larger one.
Irrigation and drainage canals provide managed flow and accessible sites. They are the practical environment in which Miromar can build, measure and operate its first modules.
Tidal channels are the larger market. The water reverses direction, the modules are larger, and the design estimate is 30–50 kW per module. Water conveyance and industrial flows are adjacent applications.
